Electrostatic precaution (ESP)
The Mitel 3000 contains electrostatic components. To ensure long-term reliability of the system, electrostatic
precautions should be taken when handling any of the system PCBs (Printed Circuit Boards) that are not enclosed
in plastic.
Lightning and surge voltage protection
Extension cabling should not be exposed to high voltage surges (for example, surges
induced by lightning or neighboring high current-carrying cables). If this is a possibility,
external protection of the main equipment and extensions using earthed line surge
protectors is essential.
